AWNING- SPECIFICATION forming part of Letters Patent No. 756,454, datedApril 5, 1904.

Application filed August 2, 1902. Serial No. 118,065. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAMASTRUP, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Awnings; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to awnings, or more particularly to the manner ormechanism for lowering and raising the same.

The object of my invention is to provide mechanism for raising andlowering awnings which is self-locking and one which is easy tomanipulate or operate, also a mechanism which can be utilized forraising and lowering awnings of considerable length, necessitatingonlythe employment of one person.

A further object of this invention is to provide a mechanism by means ofwhich the awning is uniformly rolled and one in which the awning may beadjusted and locked at any predetermined elevation.

My invention consists in providing a roller upon which the awning may bewound at one or both ends with a worm wheel properly mounted and housedand a worm which engages the worm-wheel with means for manipulating theworm.

My invention further consists in the construction and assemblage ofparts whereby the best results are attained, all of which will behereinafter fully set forth and claimed.

In the drawings, Figure 1 is a view in perspective, illustrating mypreferred construction and arrangement as applied to an awning.

- In this figure a portion only of the awningroller is shown and thecommunicating chain is broken away to bring into view certain structuralfeatures. This view also illustrates a detachable handle arrangementwhich I prefer to employ when the awning-manipulatingconnection islocated near the ground. Fig. 2 is a view in cross-section, takenthrough the worm-gearing mechanism, illustrating the same as I prefer touse it. Fig. 3 is a view in front elevation of a portion of the frontplate of a lower sprocket-wheel casing. Fig. 4 illustrates a verticalsectional view taken through the lower casing illustrated in Fig. 1.

A represents a roller to which the upper end of the awning is securedand around which the awning may be rolled. This roller may be formed ofany suitable material and has attached at one end a worm-gear B, thesaid worm-gear being so attached to the roller as to revolve with it.This worm-gear B is engaged by a worm O, which meshes with it and whenrevolved turns the said worm-gear and with the worm-gear the roller A.By the foregoing construction it will be seen that as the worm O isrevolved in one direction or the other the worm-gear B is also revolvedand with it the roller A, thus winding or unwinding the awning anydesired or suitable length. The awning may be sustained upon a framewhich is so constructed as to adjust itself to position as the awning israised or lowered. It will also be seen that regardless of the raisingor lowering of the awning it will always be locked at any point andcannot be raised or lowered except through the worm G. This feature notonly makes it possible for a single person to manipulate or raise andlower the awning, but also prevents any accident through the suddenrelease or falling of the awning, eliminating entirely both danger topedestrians or others and damage to the awning, its frame, or mechanism.

In order to provide a suitable construction for housing and lubricatingthe worm-gear mechanism and sustaining the same in posi tion, I employ ahousing D, which-entirely incloses the worm-gear mechanism and forms abearing for this end of the roller A. This casing is provided at itslower portion with outward projecting cylindrical extensions, throughwhich the ends of the worm C extend. I provide one of these extensionswith a removable plug C,through the medium of which the worm can bereadily removed from the housing. This housing is secured to thebuilding by suitable brackets or other attaching means and may besupported at its outer end by means of a bracket-bar E. For thepurpose'of lubricating the worm-gear I form the housing with an oil-wellD, within which the worm C revolves and is mounted at the ends,

and for the purpose of supplying lubricants secured to one end of saidworm, the said.

sprocket-wheel being engaged by a chain G and being in turn manipulatedto a sprocketwheel H in a housing J. This housing J may be locatedbeneath, to one side, or above the awning, according to conveniences orstructural features of the building. I prefer to provide the shaft H ofthe sprocket-wheel H with a polygonal orifice it, into which isremovably inserted the polygonal end 70 of a crank K, thus allowing thecrank to be removed, which prevents interference with the mechanism bymischievous or unauthorized persons. However, instead of the employmentof a sprocket-wheel F and chain G other means may be employed and can beemployed for manipulating the Worm-gearing, and the same may consist ofany mechanical intermediate mechanism secured in a convenient positionor desirable position above, beneath, or to one side of the worm-gearmechanism, and I do not Wish to limit my invention to themotion-communicating ,power or mechanism nor the location thereof. Alsoin regard to the position of the worm O in its relation to the worm-gearB, I would state that the same may be horizontal, vertical, or inclined,as found desirable or necessary, providing that it acts in conjunctionwith the Worm-wheel-B for the purpose and in the manner set forth. By myinvention as above set forth it will be seen that strength, safety, andeconomy are all attained both in construction and in operation.

What I claim is- 1. The combination with the casing formed with a pairof extensions, a plug fitted in one of said extensions, and theawning-roller, of a Worm-gear securedto said roller, a worm meshing withsaid gear and having its ends extending through said plug and the otherextension, a supporting means engaging the projecting ends of said Worm,and means for operating said worm.

V2. 'The combination with the housing provided at its lower end withoppositely-arranged cylindrical extensions, of a removable plug securedin the outer end of one of the said extensions, a worm arranged in thesaid v housing, said worm having its ends projecting through the saidhousing, an awning-roller having one of its ends journaled in the saidhousing abovethe said Worm, a worm-gear secured to the saidawning-roller and meshing with the said worm, brackets in which the endsof the said worm are journaled, a sprocket-wheel mounted on one end ofthe said worm, and means for rotating the said sprocket-Wheel.

3. The combination with the casing formed with an opening, and thebracket formed with an opening alining therewith, of a roller, a

worm-gear mounted thereon and being arranged in said casing, a wormarranged in said casing and meshing with said gear and having one endprojecting through the opening thereof, and through said bracket, aWheel arranged in said bracket on the end of said worm, and meansconnected to said wheel for operating the same.

Signed at Cleveland, in the county of Guyahoga and State of Ohio, this22d day of July, 1902.
